Windows 10: Question about System Restore Points for external USB SSDs...

This question is about the System Protection tab of the System Properties dialogue-box that is accessed via the Advanced system settings link in Settings App > System > About—please see the picture below. I notice that for my USB external SSD, it is labelled as "Off" in the Protection column of the Protection Settings section. Can you tell me, is this normal? Should this be the default setting for external USB SSDs in this regard? I guess it means that no "System Restore Points" are being made for the external USB SSD—which is fine, I just wanted to understand this a bit more clearly...

System Restore Point Questions

Thanks, Dave!

Suppose I go back to an earlier version of C: with the desired restore point, restore from it and create a restore point on D:, then reload the current C:. Will I be able to restore from that restore point on D:?

Step by step:

1. Enable Restore for D:
   
2. Back up the C: drive with Acronis.
   
3. Restore C: to an earlier date with the desired restore point, from the Acronis backup image.
   
4. Restore the system from the desired restore point.
   
5. See if Restore is still enabled for D:. If not, enable it there, with the same capacity as in step 1.
   
6. Disable Restore for C:.
   
7. Create a restore point. Since there's no availability on C:, it should be created on D:, and be identical to the desired restore point.
   
8. Now put C: back to the current version using the backup created in step 2.
   

Will the system now recognize that restore point on D: and let me restore from it?

(Edited to add the explanation, and step 4.)

 

System Restore Point Questions

1. This system has a C: boot drive and a D: data drive. In the System Protection dialog, selecting Confiture for D: brings up "System Protection for Data Drive (D." Does turning protection on for D: just use space on D: to store restore points for the whole system? Or does it somehow protect something on D:
   
2. I want to restore from a restore point that is no longer on the computer. But it is on an image of the C: drive created using Acronis True Image. If I use Acronis to mount the image under another drive letter, is there a way to get at the restore point? System Restore doesn't see that drive.
   

 

How to delete inactive System Image Restore Points in System Restore

Windows 10 64-bit.
When I click "show more restore points" in System Restore I see a bunch of old "system image restore points" that were deleted in past and do not correspond to any currently active restore points. Clicking any of these old restore points, I simply get an error message saying they could not be found, and to select another restore point instead.I would like to delete these restore points listings but have been unable to do so.
So far, I have tried steps mentioned below without any luck :

Disk Cleanup through (C Properties
Disable System Protection (OFF and ON) in System Protection for OS (C
Disk Space Usage to minimum (slider button all the way to the left then 'Delete all restore points for this drive'),
Delete all shown Restore points in CCleaner (the problem ones do not show here),
Reset Windows Backup to Default in Windows 10 with 'Reset_Windows_Backup.bat' utility.

Any suggestions highly welcome.
